Can you include .3MF to the list of re-compressible formats?

[tormen]

Hi.

Are there plans to include one of or all of the following formats for archive-creation:

tar.bz2 DIRECTLY from the context (shell extension) menu

.rar at all (and from the context (shell extension) menu
.ace at all (and from the context (shell extension) menu

As I was using .rar I would like to change, but only if I can also create .rar files.

Greetings,

tormen.

RAR and ACE are licensed formats.

no chance to integrate them in PA

Actually other than WinRAR and WinACE themselves, no other archivers provide creation (Extraction support is provided free-of-charge) on these two formats. They’re licensed formats and ConeXware would be charged for the license fee if PA supports these formats. It can result in the increase of PA price (only if PA really integrates these support).

```So if you read the unrar sources and if you understand how the decompressor works you can easily write a RAR compatible compressor to create RAR 2.x archives without paying any license fees. The RAR format itself (as any other archive format) and the compression algorithm (lzh) are not copyright protected. There are also some archivers out in the world which can create RAR (and ACE) archives.

Well… you should notice the License.txt from WinRAR…

here comes the quote

Neither RAR binary code, WinRAR binary code, UnRAR source or UnRAR
binary code may be used or reverse engineered to re-create the RAR
compression algorithm, which is proprietary, without written
permission of the author.

[Ricco]

And may I know which archivers support the creation of RAR and ACE? I’m interested in that.

@Ricco:

This was added in last versions of WinRAR and UnRAR (3.x) but it does not affect the previous versions of license.txt (2.x).

@Ricco:

Sure. Squeez (archiver), SpeedCommander and The Next Tool (file managers with great archive support).

[Ricco]

Thanks! But actually how is the efficiency of RAR v2.x when compared it with V3.x?

[Ricco]

I’ve tried creating RAR using Squeez. It’s quite nice though not V3.x. Hope ConeXware could consider supporting it.

RAR 2.x is much better than ZIP and today nearly everyone can extract RAR files. :D

IIRC RAR 3.x offers better compression for text files (PPMD) and for RGB files (delta coder).
